I just installed a set of Bi-xenon HID lights on my truck and they work great when the truck is off or on high beam. When the truck is running however, they flash rapidly between high and low when set to low beam. On high beam they work fine so i drove around like that all night tonight, but i need to fix them asap. I remember reading about the voltage being too high or something may casue problems? Just looking to see if this has happened to anyone. thanks

 

Yeah I remember reading a thread about the voltage being a problem on the 07's because of the CAN-BUS wiring. Try using the search feature, sorry I couldn't be more helpful, GL.

P.S. Post up the fix if you find it!
